We just saw this same behavior - I was doing a demo, Univ of Maryland and LBNL were the only sites we could maintain any consistent contact with. WPI and Dartmouth kept freezing up or dropping out and then returning..We also had problems seeing and hearing BU during a SWOF meeting today, they would appear, then freeze, then unfreeze. Our connection with these sites has been stable up until today. We're guessing that it's an ESNet issue, so we just sent email to ESNet to see if they have any insight into this.... I'll let you know what we find out.
